2008–09 Calgary Flames season

The 2008–09 Calgary Flames season was the 29th season for the Calgary Flames, and the 37th for the Flames franchise in the National Hockey League (NHL). The Flames finished second in the Northwest Division, and qualified for the 2009 Stanley Cup Playoffs as the fifth seed in the Western Conference, their fifth consecutive appearance in the post season. Their season ended when they were defeated by the Chicago Blackhawks in the Western Conference quarter-finals.

The year began with the 2008 NHL Entry Draft, which saw the Flames select forward Greg Nemisz with their first round selection. The Flames made several trades during the draft, acquiring forward Mike Cammalleri from the Los Angeles Kings as part of a three-way trade that saw Calgary deal the 17th overall pick to the Anaheim Ducks. They then sent Alex Tanguay to the Montreal Canadiens in exchange for the 25th overall pick, with each team adding lower round picks to the deal. The Flames signed forward Todd Bertuzzi during the off-season, a move that generated controversy amongst a fan base with which he had been previously unpopular. Calgary was also active at the trade deadline, making three deals, including a significant trade to add Olli Jokinen from the Phoenix Coyotes.

Jarome Iginla surpassed Theoren Fleury's franchise record of 830 points during the season, scoring his 831st point on the same night he recorded his 400th goal against the Tampa Bay Lightning as part of his second career five-point game. Iginla also scored his 400th career assist during the season, and scored his first all-star goal in his fifth appearance at the 2009 All-Star Game in Montreal. Eight players made their NHL debuts with the Flames in 2008–09.
